From the Newsweek article: "I was there one minute and the next thing I know, it's a few days later and people are telling me I was dead and came back," says Duffield. But Duffield's memory and intellect and personality all returned intact from his brush with death, as did Bondar's. This is, on some level, deeply mysterious. We experience consciousness embedded in time, a succession of mental states continually re-created in our brains, even during sleep. But when the brain shuts down, where does the mind go?"
Great question. Dude, you are holding out on us. Surely you have a theory?
